Final answer:

Kidney stones do not cause urobilinogenuria; it is caused by liver conditions like infectious hepatitis, cirrhosis, and congestive heart failure, which affect the liver's bilirubin processing.

Step-by-step explanation:

The substance that would not cause urobilinogenuria is kidney stones. Urobilinogenuria is the increased presence of urobilinogen in the urine, which can be caused by liver-related issues such as infectious hepatitis, cirrhosis, and other conditions affecting the liver's ability to process bilirubin properly. Conditions such as infectious hepatitis, cirrhosis, and congestive heart failure can lead to liver dysfunction, which in turn may lead to elevated levels of urobilinogen in the urine due to the liver's impaired ability to process and excrete bilirubin. Kidney stones, on the other hand, are primarily associated with urinary symptoms such as pain and hematuria but do not cause an increase in urobilinogen levels in urine.
